In order to protect threatened and endangered species, we conduct product stewardship training sessions each year that explain the label’s directions on pre-application site assessment and correct bait application techniques.  Additionally, we explain post-application line transect survey methods to search for and dispose of black-tailed prairie dog (BTPD) carcasses. The use of Rozol® Prairie Dog Bait (PDB) for BTPD management must incorporate measures that protect other species using the same habitat. Safeguards and risk mitigation include consultation of the Bulletins Live! Two website, end user education on in-burrow baiting methods, and ensuring that the appropriate wildlife agencies are contacted in the event listed non-target species are found in proposed treatment areas. Liphatech is committed to educating users about these requirements of the “Biological Opinion for Rozol Use on Black-tailed Prairie Dogs” (U.S. Fish and Wildlife Service, 2012).  For further information and/or assistance, please contact us.

Restricted Use Pesticide

Rozol Prairie Dog Bait (EPA Reg.#7173-286) is a Restricted Use Pesticide (RUP) approved for use by state certified pesticide applicators in CO, KS, MT, ND, NE, NM, OK, SD, TX & WY. Application is restricted to the period from October 1st through March 15th unless otherwise specified in Endangered Species Bulletins.

It is a federal offense to use any pesticide in a manner that results in the death of a threatened or endangered species. Use of Rozol PDB may pose a hazard to threatened or endangered species.

When using Rozol PDB, you must follow the measures contained in the Endangered Species Protection Bulletin valid for the area and month in which you are applying the product. Because Bulletins may change, it is mandatory to access them no more than 6 months prior to planned Rozol use.

You can access Bulletins on the EPA website or by calling 1-844-447-3813.


Black-Footed Ferrets

No baiting is allowed in re-introduction areas of black-footed ferrets. If these ferrets are found at any time before, during or after application, or during carcass searches, the US Fish & Wildlife Service’s Black-Footed Ferret Coordinator must be contacted immediately at 970-897-2730 x224. Sufficient time must be allowed for the capture and relocation of the black-footed ferret(s) before Rozol PDB application.

Northern Aplomado Falcon

In specific counties of New Mexico and Texas (indicated in red on this map), the USFWS must be contacted prior to baiting to find out where Northern Aplomado falcon habitats exist. Before bait application, a message must be left with the USFWS (New Mexico, 505-346-2525; Texas, 817-277-1100) including your name and phone number. If the USFWS does not respond within 3 days, application of bait can proceed.

This is only a partial list. For a full list, consult the EPA’s Endangered Species Protection Bulletins website. It is the responsibility of the user to read and follow all label directions.

Custom Application

If you require BTPD management on extensive acreage, or have limited manpower or time to complete treatment, please contact Liphatech for help. We will answer questions and if you are not licensed, we can put you in contact with certified pesticide applicators specialized in black-tailed prairie dog management. They have attended stewardship meetings, thoroughly understand proper application techniques, and use the latest equipment and baiting technology to ensure compliance with environmental and pesticide regulations.

Rodenticide Education

Liphatech provides education on the proper and safe use of all of the rodenticides that we manufacture and sell. Each year, we conduct numerous educational stewardship meetings on “Best Use Practices & Label Compliance” in all registered states. Based on the quality and content of our educational materials and presenters, many states offer continuing educational units (CEUs) for attendance.
